"to station err, Join AP failure"

[gsidsid]

Every time I run my modified ConnectWiFi example, I get the following:

setup begin
FW Version:
to station err
Join AP failure

This seems to be quite a popular problem, and through all the previous answers I've adapted my code such that it should work. I am running my esp8266 with an Arduino Uno in the following config:

TX->D2
RX->D3
VCC->VCC
GPIO_0->VCC
GND->GND
RST->GND

Here is the code I am using. I modified it to use SoftwareSerial, set the baud rate to 115200, and obviously filled in the appropriate SSID and password. I recall uncommenting a line in the ESP8266 header file as well, for use with my uno.

#include "ESP8266.h"
#include <SoftwareSerial.h>
#define SSID "SSID"

#define PASSWORD "PASSWORD"

SoftwareSerial mySerial(3, 2); /* RX:D3, TX:D2 */
ESP8266 wifi(mySerial);

void setup(void)
{
mySerial.begin(115200);
Serial.begin(115200);
Serial.print("setup begin\r\n");
Serial.print("FW Version: ");
Serial.println(wifi.getVersion().c_str());
if (wifi.setOprToStation()) {
Serial.print("to station ok\r\n");
} else {
Serial.print("to station err\r\n");
}
if (wifi.joinAP(SSID, PASSWORD)) {
Serial.print("Join AP success\r\n");
Serial.print("IP: ");
Serial.println(wifi.getLocalIP().c_str());
} else {
Serial.print("Join AP failure\r\n");
}
Serial.print(wifi.getLocalIP());
}

void loop(void)
{
}

If anyone has any input to provide me as to what may be causing my problem, it would be greatly appreciated. Thanks.

Try with these connections:

TX->D2
RX->D3
VCC->VCC
CH_PD->VCC
GND->GND

The example code omits the setting of the speed for Serial1. Simply adding
Serial1.begin(115200);
near the top of the setup() method resolved the problem.
